Windows 7 removes the "Customize" tab for a folder if its properties are opened via Libraries. If the same folder is opened in Explorer without accessing it via Libraries, the Customize tab is available in its Properties.
The Registry settings for modified colors for compressed files, EFS-encrypted files, item hot-tracking (single click hover) etc. are ignored by the ItemsView control in Windows 7 Explorer.
Running Explorer shell as administrator or even opening an Explorer window temporarily as administrator is not possible in Windows 7 without modifying permissions in the registry of system values because of a DCOM restriction.
Control Panel views are limited to Small icons and Large icons (which is actually Tiles view). List view, Details view, Extra large icons view, Large icons view and Medium icons view with text at the bottom are not available. The ability to show Control Panel items in groups is also removed.
IDeskBand interface and Explorer Bars are no longer supported in Windows Explorer but still supported in Internet Explorer.
Some Control Panel settings, such as Add Hardware, Bluetooth, Game Controllers, Pen and Touch, People Near Me, Tablet PC Settings, Offline Files, and Scanners and Cameras, are not listed, even under All Control Panel Items. The 32-bit Speech applet is no longer accessible through the Control Panel. While some of these settings are accessible only from Category view, or by searching, they can be made accessible via All Control Panel Items with a modification to the registry.
The slide show button from Windows Explorer starts the Windows Photo Viewer, which—unlike Windows Live Photo Gallery—does not support viewing slide shows with themes and rich transitions.
It is not possible to run the 32-bit version of Windows Explorer as a file manager or as the shell in 64-bit editions of Windows 7. 64-bit editions of Windows Vista and Windows XP allowed executing the 32-bit shell/Windows Explorer and making it the default for compatibility with shell extensions. As a result, all 32-bit shell extensions are incompatible with 64-bit versions of Windows 7.
Because of the Software Explorer being removed from Windows Defender, there is no user notification any more if UAC blocks a startup program which needs administrator privileges. Users were notified about blocked startup programs set to run as administrator in Windows Vista.
An undocumented incompatible Items view control replaces the List view control used in Windows Explorer and Start Menu breaking applications that customized the Explorer list view control. The Item view also does not support custom positioning, custom ordering, or hyperlinks, which were supported in the Windows Vista list view. Because the control is undocumented, it is not possible for developers to disable auto arrange or customize views. Because ItemsView is not considered part of the Win32 common controls reusable by developers, the sound for the Select system event no longer plays in Explorer in Windows 7.
The new items view control also ignores certain desktop.ini parameters like IconArea_Image and IconArea_Text preventing users from setting a background picture for folders. In Windows Vista, this feature was not built-in, however the list view control supported this if shell extensions or folder customization utilities which set the correct desktop.ini parameters and attributes were installed.
Each toolbar or desk band is forced to be on its own row in Windows Explorer. Windows Explorer forces the RBBS_BREAK style for every band.
When items are grouped by any criteria, multiple selection of groups by clicking the group header while holding down Ctrl is not possible as could be done in Windows Vista.
The entire folder tree view in the navigation pane cannot be collapsed vertically as could be done in Windows Explorer on Windows Vista.
Full row selection cannot be turned off for details view as was possible in Windows Vista.
The Share overlay icon for shared items in Explorer has been removed.
When navigating to a folder from a library, it is not possible to view the folder's contents in the view the user has set or customized. The folder uses the library's view.
The Remember each folder's view settings option to set Explorer to persist or not persist folder views and icon sizes per folder has been removed.
It is not possible to set Windows Explorer to remember individual folder window sizes and positions. Each folder window shares the same size, and their position cascades as more windows are opened.
Dotted lines that connect folders and subfolders do not appear as the option to turn off simple folder view is missing.
When clicking on a folder in the folders pane, it isn't automatically expanded to show its subfolders as the option to turn on simple folder view is missing.
The size of any selected item(s) is not shown on the status bar but is shown in the details pane just above the status bar. Free disk space is not shown on the status bar and the status bar is not visible by default. The details pane only shows the size of 15 selected items by default and viewing the total size of more than 15 selected items requires clicking "Show more details" each time the selection changes.
When no items are selected in a folder, neither the details pane nor the status bar show the total size of files in the folder.
Icons on the command bar in Windows Explorer and common application dialogs for Open/Save.
Disabling Auto Arrange and Align to Grid is not available in Windows Explorer windows. As a result, users can no longer manually arrange items via drag and drop within a folder; this feature is only available on the desktop.
The bar with column headers for sorting, grouping, filtering and stacking that appears for any view in Windows Vista Explorer only appears for Details view. Even in details view, the column headers only allow sorting and filtering; they no longer allow grouping and stacking. As a result, grouping must be done from the context menu in all views and sorting must also be done from the context menu in all other views except Details view. Filtering by columns can only be done in Details view.
Automatic horizontal scrolling in the left pane is removed as well as the horizontal scrollbar to manually scroll.
The Arrange By option (called Stack By in Windows Vista) is only available for libraries and folders included in libraries. In addition, users can only Stack By predefined categories depending on the library type. For example, users can only Stack by Folder, Album, Artist, Song, Genre, and Rating for the Music library, whereas in Vista, users could Stack By any properties that exist for a file (common examples would be bit rate, year, composer, play count, etc. for audio files).
Changing the sort criteria when multiple items are selected causes all items to be de-selected.
Selection of multiple items is not retained across back and forward navigation.
Tooltips for program icons only show the name of the app. They no longer show the comment field.
16-bit applications can no longer display their icon on the taskbar when running. The taskbar shows the icon for NTVDM.exe, which is the 32-bit host process for running 16-bit applications.
Quick Launch was removed in favor of 'pinned' applications. It is possible to revert to Quick Launch by manually adding it as a custom toolbar referencing %AppData%\Microsoft\Internet Explorer\Quick Launch (check citation for how-to), although Windows 7 and later have issues with Quick Launch getting automatically disabled and all its settings getting reset after a logoff or restart.
Clicking a grouped application's taskbar button or thumbnail when it is active (in the foreground) does not minimize it. Only ungrouped application buttons minimize upon being clicked again.
Icons have been removed from the tooltips for the notification area system icons such as Volume, Network, Power and the taskbar date and time.
Floating Deskbands (toolbars) are no longer available. The feature was previously deprecated in Windows Vista; all deskbands can only be pinned to the taskbar. It is no longer possible to place toolbars on the other (non-taskbar) edges of the desktop.
The ability to disable grouping (placing next to each other) similar taskbar buttons (for example, Explorer windows) is removed; users can still disable combining multiple taskbar buttons of the same type into one button.
The configurable registry option TaskbarGroupSize, which allowed fine-grained control over taskbar grouping under previous Windows versions is not supported. In Windows 7, users can only configure to either combine buttons, not combine or combine when the taskbar is full.
The number of combined taskbar windows is not calculated and shown next to the combined buttons.
Network activity animation on Network Connections icon in the notification area cannot be turned on. The Network icon only indicates the type of network (wired or wireless) and Internet connectivity.
The ability to turn off taskbar window previews (thumbnails) while still using Aero, as was configurable in Windows Vista. It is possible to turn off taskbar thumbnails when two or more windows are combined by setting a registry value, though.
The ability to disable the taskbar's "always on top" setting is removed.
When grouping is disabled, the ability to manage multiple taskbar items using multiselect (Ctrl+click) to tile, cascade, minimize or close the selected group of windows has been removed.
Only two power plans, one of them always being Balanced, and the other being "Power saver" by default, are available to choose from the taskbar. The "High Performance" power plan is hidden by default in the Control Panel.
When the taskbar is vertical, there cannot be multiple columns of icons.
Applications can no longer be excluded from appearing in the Start Menu's Most Frequently Used program list using the NoStartPage registry value as was possible in Windows XP and Windows Vista.
Programs started from outside the Start Menu such as from the Desktop, the Run dialog or from folders no longer show up in the Start Menu's Frequently Used Programs list, unless launched at least once from the Start Menu.
Classic Start menu is removed. Certain features that were present only in the Classic Start menu are not available, such as expanding the menu columns instead of scrolling, expanding folders by hovering instead of clicking, opening folders by double clicking, launching multiple programs by holding down Shift key while clicking, and creating expandable shortcuts to folders by dragging them to the Start menu.
Dynamically pinning default Internet browser and e-mail client software programs on Start menu is no longer possible. Programs can still be, however, manually pinned to the Start menu in Windows 7.
Internet Explorer Favorites and History are no longer grouped under a separate header in the Windows 7 Start Menu as they were in the Windows Vista Start Menu. They are shown under the Files group.
Windows Search features
Advanced search builder UI (Search Pane). Due to the removal of this UI, it is not possible to change the location of where to search in the same Explorer window unless at least one search has already been performed, after which Explorer shows a button to search a "Custom" scope. For saved searches (stacked views), changing the scope of the search (location for example) is no longer possible because of this removal.
The option to always search only file names has been removed from Folder Options, Search tab.
The Windows Search protocol handler addin to index network paths is incompatible with Windows 7. The Windows Search service needs to be installed and running on the remote computers to search them.
Pre-defined saved searches in the Searches folder ("Recent Documents," "Recent E-mail," "Recent Music," "Recent Pictures and Video," "Recently Changed," and "Shared by Me") have been removed.
Other shell features
The Snap To mouse pointer option to move the pointer automatically to the default button in a dialog is broken on many re-designed system and application dialog boxes and windows in Windows 7. The mouse pointer simply does not move or snap to the default button in several dialogs which are re-designed.
For security reasons, AutoPlay will support AutoRun only on optical media, such as CDs and DVDs. (Later Microsoft released KB971029 for earlier OSes to make AutoPlay Windows 7-like.)
Detection of the discontinued HD DVD format in AutoPlay.
Properties such as target command line with switches, start in path, icon and compatibility mode cannot be changed for game shortcuts in Games Explorer.
In the Personalization control panel, it is not possible to save changes to an existing theme. Changes made after choosing a theme must be saved again and the original theme deleted to prevent duplication. In previous versions of Windows, a theme file could be overwritten with the modified theme.
The 3D-Bronze, 3D-White, Conductor, Dinosaur, Hands 1, Hands 2, Variations and Windows Animated cursor schemes are removed and no longer available.
ClearType cannot be turned off entirely in order for the user interface font, Segoe UI, to maintain optimal design for certain shell components and Windows Explorer. Parts of the user interface (such as the start menu and Explorer) still use ClearType regardless of setting.
Icon size setting in the Advanced Appearance settings opened via Personalization dialog no longer affects icon sizes in Windows Explorer and on the Desktop.
Windows Media Player features
The ability to lock the player while in full-screen mode  using a 4-digit PIN has been removed.
The option to adjust the bit rate when burning data CDs has been removed.
Windows Media Player's taskbar-integrated Mini-player has been removed. The thumbnail preview which replaces this lacks volume control and a progress bar. The ability to start the miniplayer only for certain files based on specific text in their file names was also removed.
Enhancements are only accessible from Now Playing view in a floating window. They do not dock to the Now Playing window, and do not get restored when Windows Media Player is restarted. Even when manually restored, their position does not get saved.
Left/Right balance control has been removed from the graphic equalizer and is no longer possible.
Several player preferences are not saved and restored upon restarting the player. The playlist pane in Now Playing view is not shown automatically. Enhancements do not get restored when Windows Media Player is restarted. Even when manually restored, the previous position of the Now Playing window and enhancements is not retained.
The context menu entry "Find In Library" which allowed locating the Now Playing song in the library was removed.

Recently added Auto playlist is not included by default.
Total time for CDs and playlists is rounded up to the nearest minute, i.e. seconds are no longer shown.
Internet Explorer features
In Internet Explorer 8, the previous session can no longer be automatically restored the next time. The user must remember to and manually open the session the next time.
Windows Live Movie Maker does not include a proper timeline with audio edits and narration, title overlays, filter compatibility settings and other advanced options, cannot export to DV-AVI, and drops the transitions and effects from Windows Movie Maker.
The web filtering and activity reporting functionality from the in-box parental controls feature.Windows Live Family Safety replaces the web filtering functionality but its user interface for filtering and activity reporting is web-based instead of the native UI used by Windows Vista's parental controls and requires logging into a Windows Live ID (now Microsoft account).
Windows Calendar has also been removed, in favor of Windows Live Mail's calendar.
Windows Live Mail's integrated calendar supports events but not tasks, does not support subscribing, publishing, importing and exporting iCalendar files.
Windows Live Mail's integrated calendar also lacks a native events reminder. Events are reminded through e-mail instead.
Other Windows applications and features
To preserve the digital signature of a Windows Installer (MSI) file during uninstall, embedded cabinets are no longer automatically stripped off by Windows Installer 5.0 to save disk space. As a result, MSIs cached in the %Windir%\Installer directory take more disk space than earlier Windows versions with no option to disable the caching.
Transient Multimon Manager (TMM), a Windows Vista feature to automatically detect hot-Plug and Play displays as well as configure and save the multi-monitor setup is removed in favor of Win+P.
The Windows 7 On-screen keyboard removes the ability to change or specify the font as a result of which keyboard layouts of fonts which use Dingbats and Unicode characters in place of alphabetic characters can no longer be viewed.
The Windows 7 On-screen keyboard removes direct access to function keys. Function keys are now accessed using the 'Fn' key.

The 3D visuals from WinSAT benchmark have been removed.
Some features have been removed from Windows Defender such as the Software Explorer, configuration of security agents and notifications of program activities or when running startup programs as administrator.
Removable Storage Manager (RSM) has been removed, so applications that depend on it—such as NTBackup or the NTBackup Restore Tool—cannot back up to physical or virtual tape drives.
Microsoft Agent 2.0 technology was removed, breaking compatibility with Microsoft Agent applications. A separate installation package has been provided by Microsoft "due to customer feedback."
The sidebar for Desktop Gadgets was removed, although gadgets can align to any side of the screen like they did in Vista.
The Contacts, Notes and Stocks Desktop Gadgets have been removed. The Notes gadget has been replaced by Sticky Notes, allowing for both text and ink-based notes. An upgrade from Windows Vista to Windows 7 retains the user's notes from the gadget and transfers them to the Sticky Notes program.
The import, export, drag and drop and voice note features in earlier versions of Sticky Notes have been removed.
The Windows Firewall Control Panel does not allow configuring port-based filtering although the Windows Firewall with Advanced SecurityMMC-based snap-in allows this.

Calendar is a personal calendar application made by Microsoft for Microsoft Windows. It offers synchronization of calendars using Microsoft Exchange Server, Outlook.com Apple's iCloud calendar service, and Google Calendar. It supports the popular iCalendar format.
Windows 10 introduced a number of new elements, including the option to use a touch-optimized interface (known as tablet mode) or a traditional desktop interface similar to that of Windows 7 along with live tiles from Windows 8. However, unlike previous versions of Windows, where most, if not all, major features for that release were completed by its RTM, Windows 10 continues to receive major features and changes beyond its initial release to market. Microsoft describes Windows 10 as an 'operating system as a service' that will receive ongoing updates to its features and functionality. This is supplemented with the ability for enterprise environments to receive non-critical updates at a slower pace, and to use long-term support milestones that will only receive critical updates, such as security patches, over their ten-year lifespan of support. Terry Myerson, executive vice president of Microsoft's Windows and Devices Group, argued that the goal of this model was to reduce fragmentation across the Windows platform.
Some of the new features included in Windows 7 are advancements in touch, speech and handwriting recognition, support for virtual hard disks, support for additional file formats, improved performance on multi-core processors, improved boot performance, and kernel improvements.
The transition from Windows 7 to Windows 8 introduced a number of new features across various aspects of the operating system. These include a greater focus on optimizing the operating system for touchscreen-based devices (such as tablets) and cloud computing.
Compared with previous versions of Microsoft Windows, new features of Windows Vista are numerous, covering most aspects of the operating system. They include new technical features, new aspects of security and safety, new networking features, new I/O technologies, and additional management features.
While Windows Phone contains many new features, a number of capabilities and certain programs that were a part of previous versions up to Windows Mobile 6.5 were removed or changed.Until Windows Phone 6.5, the previous version did always cover the complete feature range of the predecessor version.
The following is a list of features which were present in Windows Mobile 6.5 but were removed in Windows Phone 7.0.
While Windows Vista contains many new features, a number of capabilities and certain programs that were a part of previous Windows versions up to Windows XP were removed or changed – some of which were later re-introduced in Windows 7.
The following is a list of features which were present in Windows XP but were removed in Windows Vista.
Windows DreamScene is a utility that allows videos and .gif and other optimized animations to be used as desktop wallpapers. It is one of the Windows Ultimate Extras for Windows Vista. Prior to its official announcement, DreamScene was rumored to be in creation under the names Motion Desktop and Borealis. After several months of testing, the final version was released on September 25, 2007.Rendered content included with DreamScene (such as an animated realization of the Windows Aurora background) was produced by Stardock, while photographic content was provided by the Discovery Channel. Third-party video content in MPEG or WMV format may also be used. In addition, AVI files can be played by altering the file extension. Additionally, in partnership with Dell, Microsoft released a separate DreamScene alongside its Product Red version of the Ultimate edition of Windows Vista.One of the purported advantages of DreamScene over previous methods of desktop animation is that it makes use of the GPU for display instead of the CPU, leaving the latter free to perform user tasks. To what extent this is achieved is not specified. When a full-screen program is run, such as a game or any window that is maximized, the video will automatically stop since the video will not be seen; this means it uses less GPU and CPU. The video can also be stopped manually. Content encoders need to strive for a balance between compression and file size; decompression requires the CPU, but larger files take up more memory and may cause the disk to be accessed more frequently.
Running a video in the background would have a significant impact on the battery life of mobile computers, whether or not it were rendered by the GPU, so DreamScene may display a static background when a computer is running on batteries. The software relies heavily on the Desktop Window Manager (or DWM, part of Windows Aero).
Stardock offers a chargeable add-on for Windows DreamScene, called DeskScapes. This software allows the implementation of dynamic wallpapers (".dream" files). They have released a new version (3.5), which makes the program compatible with non-Ultimate editions of Vista and newer versions of Windows (7 and 8).In Windows 7, DreamScene was replaced by a "Desktop Slideshow" feature which produces slideshow background wallpapers, but does not support videos. However, it can still be enabled via third-party tools.
Windows Phone 7 is the first release of the Windows Phone mobile client operating system, released worldwide on October 21, 2010, and in the United States on November 8, 2010. It received multiple large updates, the last being Windows Phone 7.8, which was released in January 2013 and added a few features backported from Windows Phone 8, such as a more customizable start screen.
Microsoft ended support for Windows Phone 7 on October 14, 2014. It was succeeded by Windows Phone 8, which was released on October 29, 2012.
